(57) A transmission includes a first simple planetary gear set (130) having first, second,
and third elements (132,134,136), the first element (132) of the first gear set (130)
receiving rotational motion input to the transmission, and a second simple planetary
gear set (140) having first, second, and third elements (142,144,146), the first element
(142) of the second gear set outputting rotational motion from the transmission and
the third element of (146) the second gear set (140) being connected to the third
element (136) of the first gear set (130). The elements of the first gear set (130)
include a sun gear (132), a first carrier (134), and a first ring gear (136), and
the elements of the second gear set (140) include a second sun gear (142), a second
carrier (144), and a second ring gear (146). A first clutch (150) selectively couples
the second element (134) of the first gear set (130) to the first element (142) of
the second gear set (140). A second clutch (152) selectively couples the first element
(132) of the first gear set (130) to the second element (144) of the second gear set
(140). A third clutch (154) selectively couples two elements selected from the group
consisting of the first, second, and third elements (132,134,136) of the first gear
set (130) and the third element (146) of the second gear set (140). A first brake
(156) selectively brakes the second element (144) of the second gear set (140), and
a second brake selectively brakes (158) the third element (146) of the second gear
set (140).
